Do you have to replace the CD/Radio unit with the CID radio unit?

Where can you get the TIS CD?

I was considering doing that upgrade myself after agonizing over A Garmin 660 or Pioneer AVIC-N3. I really like the way the unit opens and reveals the screen as opposed to having just a glove box. Also, everything matches as was intended. I didn't want silver or chrome anywhere on the knobs just for personal looks. I was thinking of having the Garmin secured in such a way that when I open the dash storage lid the Garmin would fold forward and lock in place. But again, another color, another blue tooth, drill through the bottom and hunt down power to keep the Garmin powered, etc. etc. If it can be done, I'll will take a stab at it. Again my only real question I had (without having seen the available connectors on the stock CD/Radio) is will it serve as a replacement to the CID Radio?
